I am taking Jazz Piano lessons at York University and my teacher and I are also doing ear training in my music lesson. My assignment is to transcribe "My Romance" by Ella Fitzgerald and "Barbados" by Charlie Parker. He expects me not to just transcribe the melody, but to know the chord voicings by ear. I am not getting marked on it, but it's something I would love to do for the rest of my life. I have no experience transcribing chord voicings. It's something I have never done before. Is there a step-by-step procedure to transcribe it systematically?
